To a/ZVZ whom it may concern.

Be it known that I, ALBERT RAYMOND, a

citizen of the United states, residing et chicago, in the county of Cook and State of Illinois, have invented anew and useful Im- V provement in Oar-Connections, which I desire e cation.

to protect by Letters' Patentof the United States, and of which the following is al speci- The object of my invention is to obviate certain objections to the usual direct connection of one car of a train with another, whereby longitudinal play of a car againstk the adjacent car and the consequent jarring are prevented when the train is being started or stopped; also, in case :of collision the liability of one platform mounting the adjacent platform, by

whichtelescopiugof the cars can take place,

- lis prevented. To overcome these objections,

instead-of coupling the cars one to another, as heretofore practiced, I mount the cars upon double trucks,l that may be either permanently connected one to another or made separable.

For a description of such construction ref,

erence is had to the accompanying drawings,

f forming a part of this specification, in which- A looking upon the roofs.

Figure l isa side elevation of cars, illustratlng the general appearance of same when coupled. Fig. 2 shows adjacent ends of two cars in vertical longitudinal section, the plan connection. f

In the elevation, Fig.'1, vertical section, Fig. 2,\and diagramvor plan,'Fig. 4,1 have illustrated a separable double truck. In ele vation, Fig. 3, is shown a single or solid truck. In the construction of my vimproved trucks thepnumber of axles and wheels are used that enter into the construction of two ordinary trucks, said wheels being indicated by letters of reference a a. and b 1). With the solid truck construction it isy designed that a train l of cars shall be inseparably connected. The adjacent ends of carsare respectively desig nated by letters A and B, ,which` ends in the present example are rounded. 1 In Fig. 2the connection of the car-bodies' with the trucks Vis best shown. The main `features of the trucks embody the usual timbers,`springs,V and other partsfor the proper support of the car-bodies, and ,areprovided with central pivotal or swivel bearings, upon which the car-bodies rest, whereby 'the latter may have lateral movement-with relation to eachother and to the truck. V.To this end a center casting, C, which, for convenience,is

designated Cwher showninsection beneath f car-end A, is provided. CastingQyis .sup-

ported upon the `bolster D'of a truck, v,and is recessed in itsupper portion suitably to rj ceivea tubular.v casting, E,the construction and relation ofthe two being such as to'per- I mit the desired pivotal,k movement ofjthecarjV upon the truck. Casting E is flangedlandse-y cured, as indicated, to the undersurface of .thecar-,body. Akingbolt,G,inserted-thronghf the car-bottom and centrally through thefcastL ings Gand E and bolster D, serves to'complete the connection of the truck and car-body.

The adjacentv ends of timbers H and Hf of the two-part truck are respectivelyv provided `with abutting plates I and I', that are rmly secured thereto by bolts or otherwise. PlatesV I and I extend upward to a level withjthe upper surface of the extending car-bottoms e'and e', where lateral extensions f1'andgfrespeetively, extend in' each direction from the center to overlap extensions e and e', which latter .l

are shouldered to receive said parts g and" y', by which a level upper` surface is obtained.

The extensions g and g constitute the'platform between cars., The shoulders of car-bot# toms e and e and the-adjacent edges thereto of extensions y' and gare curved to correspond to anarc of a circle of which the king-bolt G is the center. The dotted `lines of Fig. 4 indicate `the extreme edges of tlre'carlbottom extensions e and c. VThe coupling of the two-parttruck is eff 4fected by the application of bars .I and J', for

the accommodation'of which openings are provided through plates I andI just ,beneatlthe f Ioo l extensions g and g. Bolts n and u are inl serted through suitable apertures in extensionsg and g and through the bars, thus serving to secure said bars. Bolts n n' are de- 5 signed to be removable for convenience in coupling and uncoupling the parts of the truck, and by fitting tightly against the faces of plates I and I longitudinal movement of the coupling is prevented.

o From the foregoing description it is obvious that the only connection between cars is through their connection at C with the truck or truck parts. To prevent the attractive force from overcoming any limit of ability at 5 C to withstand such force, I provide strengthening-rods m, that respectively loop around castings C at one of their ends, and their adjacent ends in the present example are shown extended through plates I and I and secured o by nuts. They may, however, be suitably constructed at their adjacent ends to receive a bolt, and thus be coupled one to the other. The rods m serve to equalize the strain as effectually as though the carends were coupled 5 together. To close the side spa-ce between carends,I provide double doors u on each side. These doors have their support from the truck and independently of the car-bodies. The latter are provided with doors at their ends, as

`o usual. For the support of the doors u bars s are secured upon the platform-extensions g and g at the corners thereof adjacent to theV car-bodies. These bars extend up to the carroofs and have connected ytherewith cross-ex- 5 tensions s', which latter of respective sides meet centrally. To the bars s the two-part doorsu are respectively hinged and meet centrally. Suitable packing or strips of rubber or other appropriate material is applied beo tween the bars and rounded car-surfaces, that will produce a tight joint and at the same time permit the pivotal movement of the car ends. The contiguous ends of the doors are also provided with appropriate strips or packing to 5 form a tightjoint.

The upper horizontal bars or extensions, s', support a covering in two part-s meeting centrally, in which are formed channels or grooves t near their adjacent parts, that extend across o and serve to carry o and exclude water from the interior of the vestibule. Ihe steps K and Kare separated centrally, the parts being secured to the truck, and further secured by rails lvaud v', that are connected with said stepsV ;5 and to the bars s. With the solid truck shown in Fig. 3, the connection of car-bodies therewith4 is the saine as described, and the other conditions correspond, excepting, of course, no other coupling-bars are needed and the .o doors and steps of opposite sides of the platform may be single, as shown.

In Fig. 7 I have shown a modification in which the same construction exists as with the separable truck described, excepting that the `5 abutting portions of platesI and I and extensions g and g normally, only, meet centrally with relation to a line transverse to the carlengths. Asingle connecting-bar, J, is applied in this connection. It is thus apparent that the receding faces of the said plates permit flexion of one part of the truck with relation to the other, and thus adaptthe truck to curves of less radius than when the parts of said truck are inflexibly connected. With the single coupling-bar a recess is provided for the saine in the under surface of the platform or extensions g and y', as indicated by dotted lines, that equals the bar in width where the platforms meet, and is wider from that point in each direction. By this provision, in which the connecting-bar is prevented from lateral movement, the pivotalconnection of the trucksections with the bar permits the necessary flexion, and at the same time obviates any lateral sliding movement of said truck-sections with relation to each other. Pipes q' for the air-brake system are shown in Fig. 2 for the purpose of making connections, consisting of short sections supported bythe truck. These sections are respectively coupled to the pipesections of the car by flexible couplings q. A connection of adjacent ends of sections q is made by abutting the two together with interposed packing. This obviates the necessity of providing the usual hose-coupling between cars to be coupled and uncoupled when cars are to be connected or disconnected. This connection of pipes is applicable to the twopart truck as inflexibly connected, and of course not needed with a solid truck. With the modification where the truck parts are cenlOO trally connected the ordinary coupling may be used.

From the foregoing description it is obvious that in accordance with the purpose of my invention the cars are so coupled that all jars or longitudinal play of one car upon another is prevented, and there is also permitted in such construction the provision for nclosing the steps and forming a closed vestibule or entrance to the cars.

I am aware that a construction in which the ends of adjacent cars are conjointly supported upon a solid truck had been devised prior to my invention, and I do not therefore broadly claim such construction and arrangement.

Having thus described my invention, what I claim, and desire to protect by Letters Patent, is

1. In the construction of railway-cars, a truck that is adapted to pivotally support the adjacent ends of two cars, said trucks having attached thereto steps, and having at the sides thereof extending from the end of one car to the end of the adjacent car casings or doors,
